The Strictly Come Dancing stars have been married for two years, but sources insist that they are on the brink of divorce and Kevin Clifton is said to be “heartbroken”.

The professional dancers still perform together in the group routines, but beyond that they have been keeping their distance, amid reports Karen is seeing someone else.

An insider told the MailOnline: “Poor Kevin is heartbroken. It’s making it very difficult at Strictly as all the dancers knew but Kevin did not want to accept that his marriage is over.

“But sadly the writing is on the wall.”

The news comes after pictures revealed Karen, 35, out and about in London’s Primrose Hill on Sunday, apparently introducing her reported new boyfriend, accountant Stuart Wood, to her friends.

Karen was also spotted leaving her house just moments before Stuart, 27, over the weekend.

“Karen and her new bloke certainly didn’t seem to be hiding anything. They were out together with friends and looked relaxed and happy,” an onlooker reportedly told The Sun.

“But there was no hiding in corners or avoiding being spotted. They didn’t seem worried at all about the controversy about being seen together.

The sourced added: “Stuart is besotted with Karen and thinks they might have a future together.

“They’ve met up on a number of occasions over the past few weeks and are getting to know each other.”

Karen addressed rumours she and her husband were “barely talking” last week, explaining to The Sun at the OK! Beauty Awards: “We’re just a regular couple, we’ve been together for seven years and like any other relationship you have your ups and downs and nothing is ever perfect so you make it work.”
